FASTENER-- recaen.

Specification' of Letters Patent.

Patented Apr. 15, 1919.

Application led September 14, 1917. Serial No. 191,337.

Be it known that I, FRED S. CARR, a citizen of the United States, and a resident of Newton, in the county of Middlesex, Commonwealth of Massachusetta (whose ostoffice address is care of Garr Fastener gompany, Cambridge, Massachusetts,) have in vented an Improvement in Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, li ke characters on the drawings representing like parts.

This invention pertainsto improvements in fasteners, and more particularly, though not exclusively, to fasteners ofthe stud and socket type kadapted for use in the fastening of the flaps of the pockets of cartridge-belts and the like.

It is among the objects of the invention to provide a stud and socket fastener in which the chances of accidental opening are reduced to a minimumfwherein separation l of stud and socket may be readily effected,

and wherein separation of stud and socket can be edected even when the relative mani ulaton of stud and socket is imperfectly e ected through ignorance or in the excitement of battle.

In the drawings:

Figure 1 is a front/elevationof a stud and socket constituting a preferred form of one embodiment of my invention;

Fig. 2 is a section, partly in elevation, on the line 2-2 of Fig. 1;

Fig. 3 is a section on the line 3 3 of Fig. 2; Y v ig. iis an elevation` showing the rear plate of the socket proper; v ,s

Fig. 5 isa section on-the line 5-5 of Fig. 4. y. l n

Referring to the drawings of the preferred form of studv l and socket selected for purposes of illustration, I have shown a stud 6 having a neck 7 and head 8 providing a groove for engagement by resilient' jaw means herein typified by the jaw 9 and jaw 1() preferably, as shown, formed of a single piece of wire 11 recessed in a front plate 12. The front plate 12 is preferably provided with a back plate 13, providing an aperture preferably located, as shown, and in line With an aperture 14 through the front plate 1-2. The front plate Y12 is preferably providedwith projections 15- passing through opening 16 in the black plate 13 and clenched to secure the front and back plates rigidly together in the usual manner. The socket as a whole may be secured to the flap 17 of the pocket by pron s 18 passing `through and clenched von a c ench plate 19 in the usual manner. The stud 6 may be secured to the outside of the pocket in any suitable way.

As before stated, it is among the `objects of the invention to provide a fastening which, while very secure, can be readily opened even .when not manipulated `in prev ing formed to cause the jaw 10 to be wedged downwardly away from the stud and thereby to be disengaged from the shoulder 21 of 4the stud and permitting separation of the stud and socket. When the operationvis performedl as above described, the separaion of the stud and socket requires the exercise of a Very slight pull..- .It is conceivable, however, that in the excitement of battle the soldier might forget this method of operation and endeavor to open the pocket by a directoutward pull or .by an outward and upward pull on the lower flap of the pocket in the manner in Awhich the 'usual com-mercial fasteners are operated. In such case the preferred form of stud and socket fastener shown in the drawings will open because thev shoulder 21 will crowd the jaw v10 against the inclined portion of cam 20. therebywcausing said jaw V10 to ride 'down the cam 20 and to be separated from the shoulder 21. To effect separation in the latter manner requires the exercise of a much stronger pull than is necessary to separate the ordinary commercial fastener, and also a much greater pull than is necessary to separate the fa'stener shown in the drawings by a downward and outward pull. The fastener is preferably constructed so that the pull required to separate the stud and socket by a direct outward pull or by an outward and upward pull of the lower Hap is greater than any pressure likely to be exerted accidentally.

I have thus provided a stud and socket fastener separable by manipulation in two methods, one of said methods preferably requiring the exertion 'of less force than the other one. The described fastener yis very simple in construction, and certain in its operation, and has many advantages where the dual methods of operation are not necessar For instance, as a fastener for automo ile curtains the stud and socket cannot be separated by force exerted above the axis of the stud in any manner whatsoever.

While I have shown and described a preferred embodiment of my invention, it wilt be understood that changes involving omission, alteration, substitution and reversal of parts, and even changes in the mode of operation, may be made without departing from the. scope of In invention, which is best defined by the fo lowing claims.

Claimis:

l. A separable fastener comprising, in combination, a stud having a head, a socket providing a resilient jaw for engagement with one side of said stud, and a cam on said socket for engagement with said jaw to promote disengagement of s'aid jaw from said stud when said jaw is pressed toward said cam byrelative movement of said stud and socket.

2. A separable fastener com rising, in combination, a stud providing a iead and a shoulder, la socketproviding a jaw for engagement with said shoulder, and means on the casin for moving said jaw outwardly on said s oulder when said jaw is moved toward the back of said socket by relative moving apart of said stud and socket.

3. A stud and socket fastener comprising, in combination, a stud having a head and a neck; a socket having yielding jaw means; and wedge means carried by said socket, to' wedge said jaw means out of engagement with the neck of said stud, said wedge means being operated by a pull on a portion of the socket.

4. A stud and socket fastener comprising, in combination, a stud having a head and a neck, a socket providing yielding jaw means, and mieans carried by the socket effective to wedge said jaw means out of engagement with the neck of the stud.

5. A separable fastener' comprising, in`

combination, a stud having a head and a neck, a socket providing a jaw for engagement with said neck, and means on the casing for wedging said jaw out of engagement with said neck on relative tipping movement of said stud and socket.

6. A separable fastener comprising, in combination, a stud having a head and a neck, a socket providing a jaw for engagement with said neck, and means on the casing for wedging said jaw out of engagement with said neck on relative tipping movement in one direction only of said stud and socket.

7. A separable fastener comprising, in combination, a stud having a head and a neck, a socket providing a transverse jaw for engagement' with said neck, and means on the casing for wedging said transverse jaw out of engagement with said neck on relative tipping movement of said stud and socket.

8. A separable fastener comprising, in combination, a stud having a head anda recessed portion, a socket providing a transverse jaw for engagement with said recessed portion, and means permitting disengagement of said jaw from said recessed portion on downward and outward movement of the bottom of said socket relative to said` stud, or on outward and upward movement of the bottom of said socket relative to said stud.

9. A separable fastener comprising, in combination, a stud having a head and a recessed portion, a socket providing a trans verse jaw for engagement with said recessed portion, and means permitting disengagement of said jaw from said recessed portion on downward and outward movement of the bottom of said socket relative to said stud, or on outward and upward movement of the bottom of said socket relative to said stud, said stud and socket being more readily separable by said combined downward and outward movement of the bottom of said socket than by said outward and upward movement of the bottom of said socket. ,l

10. A separable fastener comprising in combination, a stud providing a recessed portion, a socket providing a jaw for e11- gagement with said recessed portion, and a back plate having a cam portion thereon for moving saidl jaw out of engagement with said recessed portion.

11. A separable fastener comprising, in combination, a stud 6 having a head 8, a socket having a front plate 12, a back plate 13, and a jaw 10, anda cam portion for engagement with the jaw 10 to impart movement thereto.

In testimony whereof, I have signed my name to this specification.
